REQUND-R-EAKE FOR SPifLING-VEHCLESQ minnie implication filed [august 20, 1913, Serial No. 725,615.

To all whom 'it may com i.'

Be it known thut i', 'Minuut Gr. COX, a citizen of the United tit-etes, residing at Albany, county of Albany, :and State of Nei' York, have invent-ed certain new and usefui improvements in iebound-lrukes for Spring-Vehicles, of which the following is n. specification. i

The invention relates to such improvements nndeonsists in the novel fonstrnetion und combii'iution of purts l'xereinnlter described and subsequenily a'hiizned.

Reference muy be hud to the accompanyingdruxi'ings, and the reference ohuruvters marked thereon, lwhirbi torni u part oit this specification.

Similar 'characters refer to similar parts in the several figures therein.

.Figure l of the drawings is u vertieul er0ssseetion`through the reni' axle of un automobile, showing, my improved reboundbrulie'Ineehunisni in eide elevation. Fig. 2 is a vertnzal :aection on u hirger soule taken longitudinally through the conteronv the rebounci-bruke-mecheinem.

The principal object of' the invention. is to retard or check the rebound ui' the springsupported body of an iutoniollvile or similar vehicle.

My improved rebouiuibralre muy be upplicd at any desired point between the two vehicle members, one of which is springsupported upon the other. in the drawings I have shown the brulie vipplied between the rear axle und body oi the vehicle,

Referring to the drawings wherein the in vention is shown in preferred form, l is the rear axle, und 2 is the frame of the body of the cur.

Mounted upon the treme, 2, is it horizontally arranged oyllnder, 3, iithm which e coil-spring, 4, is confined under compression between the rear endof the cyhnder, und e 4cup-shaped Washer, iooseiy fitting Within the cylinder, The rein: eno of the Cylinder is provided with o siotted aperture, 6. n belt, 7, connected with the Washer, 5, and extends out 'through the aperture, 6, und thence downward to the ,er exie, i, with which it is Connected ne s own. The lower well the uperture, 6, ntwurdiy extended und eonvexed 'to forni e support, 8, over belt, 7, chin dirffotion in pesei i the eylinder, J, tl e eine, which suppe' n hiring one member ofthe belt-elmnping mechanism. The other inem; ber oi" the belt-clznni'iing vmechanism is formed by a clampingdever, 9, pivoted at l0 upon the r iur end ot' the rylinder, 3, und formed with u Cl:11npingsurt;uee, l1, engugeubie with the renr'side of the belt, "I, :nul adapted to cooperate with thel support, S, to clump the belt, 7, therebetween. The dumping-lever, 9, is formed with an ot'set, 1:3` whivh oli'setprojects into the path of the belt, between the support, 8, und the .rear utile, und by engagement with the front side of the beit serves to operate theclznnl ing-lever, Si, by the tension. of the belt, to tightly (-lznnp the belt between Suid clumpingplever und Le sim-port, 8.

'The operation of the devine is :xs follows: The coil-spring, 4, being under compression instantly expands to take up the sleek in the belt. 7, whenever the body sind uxle of the vebirle nre moved toward one unother, as when the rude is suddenly raised or when the body of the vehicle is suddenly depressed. rPhe rebound due to the tendency to rennt ut' the vehifle-springs,Whiehsupporttho body upon the axle at once creates u tensirn upon the belt, 7, which tension raries in uornrilunce with the violence or quid.; ness of the rebound, causing the belt to exert u greater or less degree of pressure upon the offset, l2, to autonmticnlly operate the elun'lping-menibex', 9, and thus toreturd the paying out of the belt, 7, thereby braking or checking the rebound.

l' have shown a preferred form of belt2 7, inside of u plurality of separate plies which 'tend to creep one upon another in passing around the eonvexed support, 8, which Creeping movement of the belt-plies relutively to each other, aswell as' the movement of both plies around the siipport, 8, is resisted und retarded by the clampingmechanism,

llibut I clari new und desire' to secure by Letters Patent isi. rihe combinutionu'th u pair of ineinbers one spring-supported upon the other; of e take-np sprintf mounted upon one of seid members; e eli-connection between seid trike-rp spring und the other of said members: and belt-rlumping-meelmnism uutometiculiy actuated by tension of the beit,

The eomliiinetinn w' l here one springsuppnrie I of a take-up sprir; mounted upon one of a support over which the belt slides, and a,

clamplng-lever engageable with one side of the belt to force the belt against said support, and having a member in engagement with the 'opposite side of said belt lin the path between said support and said other member.

4. The combination with a pair of members one springsupported upon the other;

of a cylinder mounted upon one of saidmembers; a coil-spring confined Within sa'id cylinder; a belt connected at one end with said coil-spring and at the other end with the other of said members; and belt-clamping-mechai'iism engageable with said belt between said springand the other member, Said clamping-mechanism having a movable member over which seid belt passes adapted to be automatically actuated by the tension of the belt.

5. The?combinationvwitli a pair of members one'vspring-supported upon the other; of a ta ce-up spring, and clamping-mecha nism mounted upon one of said members; and a belt composed of a plurality of separate plies connecting said take-up spring with the other member and changing direction at the clwiping-mechanism, said clamping-mechanism comprising a support over which the belt changes direction and a clamping-member coperative With said support, automatically operated by the tension of 'the belt.

G. The combination with a pair of members, one spring-supported uponthe other; of a take-up spring mounted upon one of said members; a belt connecting said takeup spring with the other member, said belt being composed of a plurality of separate plies-capable of a limited relative longitudinal movement; andbeltclamping mechanism embracing both plies of the belt, comprising in part a support over which said belt changes direction.

In testimonyT whereof, I have hereunto set my hand this 14th day of August, 1913.
